Abstract: PURPOSE:To decrease the measuring error over the entire part of a system and to provide higher reliability by subjecting the reflected light of a measuring element and plural reference signals to A/D conversion, compensating the fluctuation in the quantity of light and calculating the error of the A/D conversion in the stage of inputting the reference signals. CONSTITUTION:A ray 2 from a light source 1 is irradiated to a measuring element 6 by opening a shutter vane 8 provided on the optical path thereof and the reflected light thereof is transmitted to a photodetector 20. A part of the ray 2 is branched from the optical path thereof and is applied as reference light to a photodetector 21. The respective output signals from the photodetectors 20 and 21 are differentially amplified by a compensating circuit 40.
